Built Up Platform For Shower Stall ........ Help

I am remodeling a utility room and turning it into a bathroom. The problem I am having right now is building a platform to set the shower on. The existing floor is concrete and cutting or drilling a hole is not an option.

I need to know if a 2x4 frame will allow me enough room to run the drain or will I need a 2x6 or even higher frame?

Is there a standard distance from the bottom of the shower (floor level) to the bottom of the trap? Thanks in advance.

I'm not a pro plumber, but IMHO, your main concern should be getting the height to allow the 1/4" per linear foot slope for the shower drain line toward the main drain line. That also should allow for the trap depth. I doubt that 2X4 or 2X6 will do it.
Work it all out and dry-fit it before finishing to make certain.
Good luck!

Hey Capt Black...I'm with the same predicament as you here. What did you end up doing and how does it work??

Where are you tapping into a drain line? From the limited research I've done for my future basement bathroom, they say that you need at least 2x6 so you can install a p-trap. You'll have to figure out how high you are tapping into an existing drain, how much linear distance you are from that point and calculate at least 1/4" per linear foot and then add the p-trap to that height.

Capt Black, You need to do some math to figure it out. Determine how much "fall" you need to get to the drainline you are tying into (1/4" per foot fall). Make sure you also have enough height at the drainline to install the tee above the concrete. I am guessing that you will need at least 2x8 for the base. Don't forget the vent line for the shower drain or you will have sewer gas problems with the shower trap being sucked out. Hope this helps.

Jack hammer! This is not a $30,000 job. Repiping an entire commercial kitchen like I did a few months ago was $32,000 and that included a 1500 gal grease interceptor outside. Where are you trying to go with this shower drain? I am asuming there will be a toilet in this bathroom so how is the pipe for that running?
